I am working on a small script where there are some list items. If you refer to the below code you will notice that there are 15 list items. Now I just want to display 9 of them say the user log's in the 1st time the first nine should be displayed now if he clicks on list no. 7 then list no 3, 4, 5, 6, 7, 8, 9, 10, 11 should be displayed.
Will I have to give id to each and every list?
Thanks

You could do this with CSS and JavaScript or just JavaScript.
CSS:
to Hide
display: none;
to Show
display: block;
Then give each an id. Set the hidden to display:none then in JavaScript set to block when the user clicks on number 7.
OR
JavaScript:
Write the HTML of the List based on user interaction
document.write('<li><a href="13">13</a></li>');
And use a function call for Number Seven to write the entire list when clicked.
You could also place this in a DIV and re-write the list in the DIV based on user interaction.
